Definitions

  • the present invention relates to irons steam iron which include a heated soleplate with a series of holes in its underside steam outlet and in its upper side a room vaporization in connection with said holes and communicating with a water tank.
  • irons steam iron which also have a clean pump take a dose of water from the tank and send this dose, via a selection either in the vaporization chamber so suddenly obtain an abundant emission of vapor at through the holes in the sole, either towards a sprayer cold water located in the front part of the iron, this pump being of the piston type moving in a suction chamber which is formed in the body of the pump and which opens into the tank via a valve anti-return. See, for example, document EP-A-0 080 634.
  • the sudden emission steam or "super-steamer” is useful for carrying out the marking folds in thick fabrics, for example pants folds while spraying water cold is used, for example, to eliminate wrinkles, in particular on excessively dry fabrics.
  • the selection device ensuring the choice between supervisor and spray includes a selector which is rotatably mounted in a fixed annular bowl provided at its bottom with two angularly spaced orifices, namely an injection orifice connected to the chamber and a spray orifice connected to the sprayer, and which carries a flexible shutter forming a clean rotary joint to close either of the two orifices according to the angular position of this member selector.
  • a rotating joint is still subject in time to wear by friction on the bottom of the bowl which inevitably leads to the appearance of water leaks, affecting the proper functioning iron.
  • the realization and mounting of this rotary type selector member are relatively complex and therefore particularly expensive for mass production of irons.
  • the object of the invention is to remedy these drawbacks and make an equipped steam iron a selection device - super-steamer or spray - which is simple, economical and highly reliable.
  • Document FR-A-2 230 786 further describes an iron iron in which the selection between spraying and supervisor is provided by means of a two-position valve which is linked to the pump actuation button.
  • the device for selection includes a deformable membrane with a substantially flat lower part with two protrusions each acting as a valve and being held in place tightly in a cup which is formed in the upper part of the piston of the pump and whose bottom, on the one hand, communicates with the suction chamber through a discharge bore in said piston, and on the other hand, has two orifices, namely an injection orifice connected to the vaporization chamber and a spray orifice connected to the sprayer, the two diaphragm valves being located respectively at the level of the two orifices and their operation being subject respectively to two manual control buttons, respectively called spray and spray, which protrude from the upper part of the iron and including the spray button is related to the valve associated with the orifice while the spray button is related to the valve associated with the orifice injection, the membrane passing from a rest position, defined when the pump is primed, in which the two valves are closed and seal respectively the two orifices, at a working position, defined when either
  • this deformable membrane with double valve the opening of which is selectively subject to pressure pumped water, constitutes a simple organ and unalterable ensuring, according to the choice of the user, selection between the steam and spray functions, and all the more so since the double-flap membrane is integrated in the pump.
  • the steam iron 10 shown schematically in Figure 1 includes a heated soleplate 11 presenting, on its underside, a series of steam outlet holes 12 and, in its upper face, a vaporization chamber 14 in relation to the holes 12 and communicating with a water tank 17.
  • This iron further comprises a pump, designated by the general reference 20, whose body 21 has an axis of vertical symmetry XX '(figures 2, 3 and 4) and which is clean to draw from the reservoir 17 a dose of water and to send this dose, via a device selection 24 which will be described later, either in the vaporization chamber 14 in order to suddenly obtain a abundant emission of steam through holes 12 of the sole 11, either to a cold water sprayer 25, of known structure, located in the anterior region iron.
  • a pump designated by the general reference 20, whose body 21 has an axis of vertical symmetry XX '(figures 2, 3 and 4) and which is clean to draw from the reservoir 17 a dose of water and to send this dose, via a device selection 24 which will be described later, either in the vaporization chamber 14 in order to suddenly obtain a abundant emission of steam through holes 12 of the sole 11, either to a cold water sprayer 25, of known structure, located in the anterior region iron.
  • the pump 20 is of the piston type 27 moving so watertight, under the action of a spring 29 disposed axially, in a cylindrical suction chamber 31 provided axially in the body 21 of the pump and opening at 33 into the reservoir 17 (FIG. 1) via a non-return valve currently consisting of a ball 35 cooperating with a conical seat 36.
  • the piston 27 of the pump 20 extends in its part upper by a cylindrical cup 39 whose bottom 40 communicates with the suction chamber 31 by a cylindrical discharge bore 42 made axially in the piston 27, and has two openings symmetrically with respect to the axis XX 'of the body 21 of the pump, namely an injection orifice 44 connected to the iron vaporization chamber 14 ( Figure 1) and an orifice spray 45 connected to sprayer 25.
  • the two orifices 44 and 45 open respectively in two opposite conduits 47 and 48 orthogonal to the axis XX ′ of the body 21 of the pump and forming an integral part piston 27 of the pump; conduit 47, in which opens the injection orifice 44, is connected to the vaporization chamber 14 by flexible tubing injection 51, while the conduit 48, in which opens spray opening 45, is connected to the sprayer 25 by another flexible injection tube 53.
  • the selection device 24 illustrated in Figures 2 to 4 and intended to authorize the choice between sudden emission of steam or "supervisor” and spraying has a membrane flexible deformable 56, held in place in the cup 39 of the piston 27 of the pump and having a lower part 56a substantially flat provided with two protrusions 58 and 59 each acting as a valve in being located respectively at the level of the two orifices 44 and 45;
  • the two valves 59 and 58 of the membrane 56 have an operation subject respectively to two manual control buttons, called spraying buttons respectively 62 and spray 63, which protrude one behind the other from the top of the iron ( Figure 1) being arranged symmetrically with respect to the axis XX 'of the body 21 of the pump, and the button of which vaporization 62 is in relation to the associated valve 59 to spray port 45, while the spray button spray 63 is related to the associated valve 58 at the injection port 44, the membrane 56 passing a rest position, defined when the pump 20 is primed, in which the two valves
  • the membrane 56 has a substantially U-shaped cross section whose bottom 56a carries the two valves 58 and 59, and the edge of which end device 66 is kept in abutment against the internal surface of the cup 39 by means of a part 68 forming a closure plug for the cup.
  • the two spray buttons, respectively 62 and spray 63 are push buttons, optionally each equipped with a return spring, and provided with actuating rods 62a, 63a which are engaged in two bores 71 and 72 respectively vertically in the plug 68, at plumb with the two valves 59, 58 of the membrane 56.
  • these two push buttons 62,63 could be replaced by any other equivalent means, such as, by example, by two toggle buttons and could also be arranged laterally next to each other relative to the top of the iron, without depart from the spirit of the invention.
  • the assembly formed by the membrane 56 and the two valves 58.59 is made of a material elastomer, such as for example a silicone, and constitutes in itself a seal between the piston 27 of the pump and blanking plug 68.
  • the piston 27, the membrane 56 with two valves, the blanking plug 68 and the two control buttons 62.63 constitute a unitary whole, thus facilitating notably the mounting of the pump inside the iron.
  • the pump 20, under the effect of the spring 29, is then reboots as soon as you release the spray button 62.
  • section of bore 42 is more large as the cross section of the two holes, respectively injection 44 and spray 45, and outlet 33 so as to prevent any backflow of water with certainty by the spray orifice due to the pressure generated by the sudden evaporation of water in the vaporization chamber when iron is used in its function supervisor.
  • non-return valve 75 in the event of significant overpressure in the vaporization chamber 14, it is advantageous to interpose a non-return valve, designated at 75 on the Figure 1, between the outlet of pump 20, on the side of the injection orifice 44, and the entrance to the vaporization 14.
  • This non-return valve 75 is made up, for example, by a perforated membrane displaceable under the action of the pressure prevailing in the vaporization chamber 14 and clean to come close the exit of the injection manifold 51.
  • this non-return valve 75 could be established by any other means equivalent, such as, for example, by a single ball or again by a flange formed in the cap shutter 68, directly above the valve 58 associated with the injection port 44, without leaving the frame for this of the invention.
